Worth the price
This is great! I have stomach issues and cannot have soy, dairy or caffeine. This was perfect! Tastes awesome, works great as a post workout shake or I can add fruit and half 2% lactaid milk to make it a meal replacement and it works perfectly and keeps me full until my next meal. Easy to mix with blender or bottle shaker. Doesn’t leave clumps like other powers do. The ingredient list is great and doesn’t have so many additives or things you cannot pronounce. The price is high but you’re getting a great quality product and it’s worth the $70. I eventually accumulate my points and get one free or half off.

Love this stuff
Gotta love the G6 Prolific isolate. I like the chocolate and use it as a "sweet" treat protein. I use it in oatmeal, and post workout shakes. The flavor is great and the nutrition label facts are great too. I would highly recommend this product.

I really love this protein because it doesn't make me feel bloated like other proteins do. Plus, G6 uses natural ingredients with stevia so thats nice. I also like that this mixes well with pretty much anything.

Its so hard these days to find a solid protein powder. This has none of that extra stuff like fillers and un-natural additives. Its one of, if not the cleanest, powder I can find. I will continue to use and recommend this product.
February 16, 2018
What a solid product! Its soy-free, gluten, free, and lactose free- so if you're sensitive to any of those you can feel confident about taking this product. I truly recommend.

As a meal replacement is it filling? Can it be taking in the evening if you get hungry? I am a 72 old women who walk, is this to much protein for me.

will this add muscle?
A shopper on Mar 29, 2018
BEST ANSWER: Loaded question. NO supplement actually builds muscle, they only AID in the building of muscle fibers. It will only help support protein synthesis (like ALL protein powders/supplements) which is how muscle is developed. The only way to add/build muscle is to work out then get enough sleep. Working out causes the damage to the muscle tissue that needs to be repaired. Muscle is only repaired/built when we sleep. Using a protein powder will only assist in providing the building block of muscle that your body uses for repair.
It says lactose free but at the bottom it says contains milk?
